Abstract: A connector that has three input/output ports and that can connect any two of the ports is used with a cable box that selects a channel from a CATV signal for a VCR and a TV, which also have respective connecting portions for inputting and outputting an audio signal, a video signal, and control data. The connecting portions of the video equipment are connected by a cable and a connector, so that the cable box, the VCR, and the TV are linked to each other. Each of the cable box, the VCR, and the TV can be set to a category such as "master", to control equipment, or "slave", to be under control, and also can be set to determine the order of priority. The "master" equipment with the highest priority determines the addresses for each unit of the equipment based on such categories. The "master" equipment can control each unit of the equipment using the addresses.

Abstract: In a projector comprising three image forming devices, disposed between a separation optical section and a combination optical section, for processing a red, a green, and a blue light beams, at least one of the three image forming devices comprises a polarization direction converting means, such as a halfwave plate for converting polarization direction for one of the red, the green, and the blue image light beams so that one of a color combining dichroic mirrors has a cutoff wavelength of spectral characteristic which shifts toward outside for one of the red, the green, and the blue central wavelengths from that of one of a color separating dichroic mirrors. The halfwave plate may be disposed in a light-leaving side of at least one of the three image forming devices.

Abstract: An input signal is inputted to an A/D converter through an amplifier and is converted into a digital input signal. A vertical synchronizing pulse and a horizontal synchronizing pulse are taken out of the output signal of the amplifier by means of a TV synchronizing separator and inputted to a trigger gate and selector circuit. A delay timer and a timing control circuit are operated by a selected synchronizing pulse, and the data applied with A/D conversion are stored in a memory in accordance with a set delay time and sampling synchronization. The stored data are read by means of a CPU circuit. The state of a burst signal is decided by the CPU circuit, and separation of eight fields is performed by combining that state with a set state of the TV synchronizing separator.

Abstract: A vestigial-sideband amplitude-modulation transmitter using a balanced modulator for generating a suppressed carrier that is in quadrature phasing with the video carrier of a television signal receives as modulating signal a binary phase-shift-keying (BPSK) signal encoding digital signals. The quadrature transmission reduces the visibility of the lower-frequency PSK sidebands in the TV signal as viewed on screen. The symbol rate of the PSK is made to be a multiple of the horizontal line scan rate of video signal. To reduce the visibility of the higher-frequency PSK sidebands in the TV signal as viewed on screen, the BPSK is transmitted twice during respective frames of successive pairs of data frames, which data frames recur at the same rate as video frames. To reduce the interference of video with the PSK, the PSK is subjected to partial-response filtering at the transmitter and is highpass line-comb filtered at the digital signal receiver.

Abstract: The apparatus and method described herein shows a system of determining the delay of a delayed version of a sequence of images with respect to a relatively undelayed version. The system operates to take multiple samples of the delayed and undelayed versions at approximately the same sample position on the image and to correlate these samples over multiple image frames to determine which of a plurality of delayed images most closely match a given undelayed image. By knowing which delayed image frame most closely matches a given undelayed image frame it is shown to arrive at a coarse number of frames of delay. A fine delay measurement is achieved by adding a measure of the instantaneous frame to frame delay with respect to a known corresponding feature of the respective video type signals. The invention is also useful for comparing a given image to other images to determine the closest match.

Abstract: In a video communication system including a sending terminal and a receiving terminal connected via a packet switching network, a receiving terminal which has detected loss of a video packet sets a video output into a freeze status and transmits a refresh request command to the sending terminal. Upon receiving the refresh request command, the sending terminal requests a video coder unit to execute refreshing and transmits a series of video packets beginning from an INTRA frame. Upon receiving a packet of the INTRA frame, the receiving terminal releases the freeze status and restarts video information decoding.

Abstract: A color television camera includes a panchromatic light sensor such as a CCD imager. Light from a scene to be imaged is filtered by an electronically controlled light filter such as an etalon, which is scanned from color to color at the field rate, so that the image for each field is generated by a different color. The periodic spectral line or spectral band response of a single etalon is improved by a cascade of two etalons with different periodicity, which pass only a single spectral line or band. When an RGB color sequence is used, a complete color signal frame is generated in three fields. The imager may be operated at a field rate higher than the standard field rate, such as 90 Hz. for use with conventional 30 Hz. color frame rate, and a memory may be coupled to the output of the imager to store the three-field sequence of signals which occurs during each standard color frame, so that a complete color signal is available during each standard color frame.

Abstract: A solid-state array scanner with a color filter at each pixel sensor is provided to accomplish color scanning of color images with a set of pixels sensors for each color pixel. In addition, a scaler device is provided for selectively scaling the output pixel signal from each pixel sensor to correct for color filter loss when scanning black/white images. Thus, while a set of pixel signals must be combined for each color pixel in color mode scanning, in mono mode scanning of black/white images, the pixel signal from each pixel signal may be used. An address means selectively addresses each solid-state pixel sensor device in the array for readout of the illumination intensity, or pixel signal, sensed by that device. Each pixel sensor will have a given color filter dependent upon the sensor's location in the array. From the address of the pixel sensor, the scaler value to compensate for the color filter in mono mode can be selected.
